    摘要： A method and system are provided for aligning fibers in an electrospinning process. A jet of a fiberizable material is directed towards an uncharged collector from a dispensing location that is spaced apart from the collector. While the fiberizable material is directed towards the collector, an elliptical electric field is generated via the electrically charged dispenser and an oppositely-charged control location. The field spans between the dispensing location and the control location that is within line-of-sight of the dispensing location, and impinges upon at least a portion of the collector. Various combinations of numbers and geometries of dispensers, collectors, and electrodes can be used.

    摘要： A processable electrically conductive polymeric complex comprising a polyelectrolyte having acid functional groups and a conductive polymer selected from the group consisting of polyaniline, polypyrrole, polythiophene, poly(phenylene sulfide), the conductive polymer ionically bound to the polyelectrolyte. The mole ratio of the monomers which form the conductive polymer to the acid functional groups of the polyelectrolyte is ≧1. The polymeric complex is made by a template-guided chemical polymerization process which comprises adsorbing the monomers onto the polyelectrolyte in a mixture of alcohol and water to form a polyectrolyte adduct, emulsifying the polyelectrolyte adduct in an acid to form an emulsified polyelectrolyte adduct and oxidatively polymerizing the emulsified polyectrolyte adduct. The polymeric complex is water insoluble when dried as a coating on a substrate.

    摘要： A compact full-range loudspeaker system includes an elongated enclosure having two open ends joined by a hollow interior, which enclosure may be of fixed dimension or telescoping, and has a full-range speaker mounted at each end of the cylindrical enclosure. The enclosure length is set in a range governed by the small speaker size to maximize the system response, particularly in the lower frequency range, and a dampening material is provided to construct the enclosure to minimize the structural acoustic response of the enclosure when being driven. A pair of miniature sound boards may be flat, polymer surfaces mounted to a base and positioned at each end of the cylindrical enclosure at an angle facing each speaker for reflecting sound waves emanating from the speaker in accordance with the positioning of the cylindrical enclosure to create an effective sound stage and control directionality.
